package中添加图片资源并部署到Visual Studio中时，图片资源的文件路径是什么？
[英]What is the file path for image resources when you add them during package and deploy in Visual Studio?
问题描述
I have made a html file that outputs a receipt for my C# application.
我制作了一个 html 文件，输出了我的 C# 申请的收据。 In the html report I have a logo at the top of the receipt.在 html 报告中，我在收据顶部有一个徽标。 The image is in the debug folder and it works fine when I run it debugging.该图像位于调试文件夹中，当我运行它进行调试时它工作正常。
However when I package and deploy my application, the receipt loses the image.但是，当我 package 并部署我的应用程序时，收据丢失了图像。 I add the image as a resource when I package and deploy so I know its there.我在 package 和部署时将图像添加为资源，所以我知道它在那里。 I am assuming that I need to put the full path to access the image.我假设我需要输入完整路径才能访问图像。
However, I do not know what the path will be when we package and deploy.但是，我不知道我们 package 和部署时的路径是什么。 Where are the image resources we add when we package and deploy stored when we install the application?我们package时添加的图片资源和安装应用时deploy存储的图片资源在哪里？
Here is my function that creates my html file.这是我的 function，它创建了我的 html 文件。 Where I put the image source what do I need to put to get the logo to show up when I debug and when I package and deploy?我把图像源放在哪里，我需要放什么才能在我调试和部署 package 时显示徽标？

if your logo isn't an huge image file, you could set it directly into the markup, using Base64 encoding, that transform an image into a string, to use instead of path.如果您的徽标不是一个巨大的图像文件，您可以使用 Base64 编码将其直接设置到标记中，将图像转换为字符串，以代替路径使用。
You can convert your logo into Base64 string using an online service like this您可以使用这样的在线服务将徽标转换为 Base64 字符串
and then add it to your HTML output this way然后通过这种方式将其添加到您的 HTML output
<img src="data:image/png;base64,#past here your image encoded text#">
